Emerald Ash Borer Information

What is the emerald ash borer?

The emerald ash borer is a small, ½-inch-long and 1/8-inch-wide beetle native to Asia. The average adult can easily fit on a penny. Beetles are usually only visible from May to July. The first reported case in the United States was in 2002 in Michigan. Because of the infestation since that time, nearly 20 million ash trees have died in Michigan, Indiana and Ohio. The EAB has been found in several Illinois counties.

What if I suspect that my ash tree(s) is infested by EAB?

If the tree is a public parkway tree, call the Village of Glenview Public Works Department during business hours at (847) 657-3030. If it is an ash tree on private property, consult a private tree service with a certified arborist. You may choose to have the tree removed or attempt to protect it with insecticidal treatments. A tree removal permit is needed before removing a privately-owned tree of 16 inches or larger in diameter. Permits are required by Village ordinance to ensure that large healthy trees are not removed; permits are easily obtained for most ash trees. A tree-removal permit form is available here or at the Community Development Department front desk at Village Hall, 1225 Waukegan Road. Return the completed application to the department for processing and call (847) 904-4330 for any questions or further information.
